Living World Drops for Guinea Pigs are field berry-flavoured morsels enriched with minerals and vitamins – including Vitamin C, which is vital to Guinea Pigs, as they do not manufacture it on their own. The Drops can be used as a general daily treat. They can also be used as a training aid, inserted in treat balls for behavioral enrichment to prevent boredom, or broken up and scattered to induce natural foraging behavior.
